In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7050 are massively better than the Intel GFX 2560x1440.

The GFX 2560x1440 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The GeForce 7050 was released over three years more recently than the GFX 2560x1440, and so the GeForce 7050 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GFX 2560x1440 when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce 7050 has 128 MB video memory, but the GFX 2560x1440 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 7050 has 2 Shader Processing Units but the GFX 2560x1440 does not have an entry, so the two GPUs cannot be reliably compared in this area.
